LOCKING CLIP.

Application led August 4, 1926. Serial No. 126,953.

The present invention relates to new and useful improvements in clips, and it pertains more particularly to that class of clips employed by hair dressers in connection with appliances for permanently waving hair.

Among the several objects of the invention are to provide a clip which will securely grip an article to which it may be applied without injury thereto; to provide a clip which in its attachment to an article will be self-locking; to provide a clip which may quickly and easily be detached from an article to which it has been attached or by which it is carried; and so to construct the clip that its several parts may be manufactured at small cost and readily assembled.

With the above and other objects in View, reference is had to the accompanying drawings in which- Figure 1 is a view in side elevation of the improved clip in its open position;

Figure 2 is a similar view showing the clip in closed position; and

Figure 3 is a detail sectional view showing the manner of use of the clip.

A preferred embodiment of a clip constructed in accordance with the present invention includes two jaws 10 and 12 hinged together as by a hinge pin 14. Each jaw is provided with a gripping edge, preferably of curved form, as shown at 16 and 18, respectively, in the drawings.

The jaw 10 preferably comprises two plates 2() and 22. maintained in spaced relation to each other by studs or the like 24, 26 and the hinge pin 14 which forms the heretofore mentioned pivot of relative movement of the jaws 10 and 12. Upon one end of the jaw 10, an operating handle 28 is provided, and said operating handle is preferably formed integral with the plates 20 and 22 forming the jaw 10.

The jaw 12 is preferably formed from a. single piece of material, and is provided near its pivoted end with an operating handle 30, and near its tree end with an operating handle 32 and each of these operating handles 30 and 32 may be formed integral with the jaw 12. Projecting from the jaw 12 is an arm 34, preferably of arcuate form and this arm is formed or otherwise provided with a plurality of rack teeth 36, the arm 34 being located at a point substantially midway between the ends of the jaw 12 and being preferably integral therewith.

Carried by the jaw 10, and preferably pivoted between the plates 20 and 22 upon the stud 26, is a locking lever or pawl 38 for retaining the pivoted jaws 10 and 12 in gripping position. This locking lever 38 is provided upon one end with a tooth or dog 40 for co-operation with the rack teeth 36 of the arm 34 to lock the jaws 1() and 12 in gripping position, it being obvious that the rack teeth 36 of the arm 34 engage with the tooth or dog 4() when the jaws are moved to their closed or locking position. To maintain the tooth or dog 40 normally in engagement with the rack teeth of the arm 34, a spring 42 is provided. This spring 42 may be carried by the stud 24 and has one of its free ends engaging the locking lever 38 as indicated at 44 in the drawings. Movement of the locking lever 38 is limited in one direction by means of a stop 48 integral with the plate 22 against which said locking lever engages.

For rocking the locking lever 38 to disengage the tooth or dog 40 from the ratchet teeth 36 on the arm 34 of the jaw 12, said locking lever is provided with an operating handle 46 which occupies a position sufficiently close to the handle 30 of the jaw 12 to permit of the two being simultaneously gripped when the jaws 1() and 12 are in their gripping or clamping position. Pressure of the handles 46 and 30 toward each other rocks the locking lever 38 to disengage the tooth or dog 40 and at the same time eii'ects the movement of the jaws 1() and 12 to their open position.

When used in connection with permanent waving apparatus, after the chemical containing pad B and the paper tube C have been placed about the coiled strand of hair, which latter is designated by the reference character A in Figure 3 of the drawings, which is common procedure in the practice of the ordinary method of imparting a permanent wave to the hair. the end of the paper tube adjacent the scalp is gripped and closed by means of the clip in the following manner: It the clip be in its closed condition, the two operating handles 30 and 46 are grasped in one hand of the operator and sufficient pressure exerted thereon to cause the locking lever 38 to release the aw 12, whereupon the jaws 10 and 12 move to their open position shown in Fig. 1. The clip is then passed about the end of the tube C which is adjacent to the scalp and pressure then applied 'to the operating handles 28 and 32, for example, by the other hand of the thus moving the jaws 10 and 12 to gripping position as Shown in Figures Q and 3.

Upon movementl ot the jaws to the Closed or gripping position. the tooth or dog 40 of the locking lever 3S will engage with the raeli teeth 36 and loel; the jaws 10 and 12 in their tube-gripping position until released bj' the operator applying pressure to the operating handles 30 and 16 in the manner heretofore described.

From the foregoing it will be apparent that the present invention provides a new and improved Clip whieli may be applied to and removed from operative position with faeilitv and without injurjv to the hair whieh is lbeing treated. Vfhile in this :ip-- plieation one embi'idiinent of the invention has been illustrated. it is to be understood that the invention is not. limited thereto. and that it ma)Y be embodied in other 'forms which Come within the seope of the appended Claims.
